558 AM AST THU FEB 20 2020
DISCUSSION
DRYING CONDITIONS PERSIST ACROSS THE REGION, WITH VERY LITTLE IN
THE WAY OF WETTING RAINS SEEN YESTERDAY, ESPECIALLY IN
SOUTHWESTERN PUERTO RICO. AND, THOUGH WINDS ARE SUBSIDING SOMEWHAT
TODAY COMPARED TO YESTERDAY, THEY WILL REMAIN AROUND 10 TO 20 MPH,
WITH STRONGER GUSTS POSSIBLE. NO SIGNIFICANT PRECIPITATION IS
EXPECTED TODAY, AND MOSTLY SUNNY SKIES WILL GENERALLY PREVAIL.
FURTHERMORE, A GENERALLY DRIER AIRMASS IS PUSHING ACROSS THE LOCAL
ISLANDS TODAY INTO TOMORROW. KBDI IS APPROACHING THE CRITICAL
THRESHOLDS IN CABO ROJO AS OF YESTERDAY, WITH A VALUE OF 538. AT
CAMP SANTIAGO, THE KBDI IS IN EXCESS OF CRITICAL THRESHOLDS, WITH
A VALUE OF 678. WITH THESE FACTORS IN CONSIDERATION, THE FIRE
DANGER LEVEL IS CONSIDERED ELEVATED IN THE SOUTHWEST AND SOUTHEAST
OF PUERTO RICO, THOUGH IT REMAINS LOW ELSEWHERE IN PUERTO RICO AND
THE U.S. VIRGIN ISLANDS.
